Description

Electric pots and home appliances {ELECTRIC KETTLE AND HOME APPLIACNE}

The present invention relates to an electric pot and a household appliance.

There are various types of home appliances that heat contents using a heat source. For example, there are rice cookers, induction cookers, electric pots, hot air heaters, and the like.

In particular, the electric pot is widely used at home because it has a convenient structure as a home appliance for cooking or sterilizing mainly by heating liquid food.

The electric pot uses a heater such as a heating coil to sterilize the beverage or liquid contained therein by raising it to 100 degrees or more to heat the internal material. Therefore, the contents that have just been heated are inevitably high enough to be difficult to ingest, and the user often ingests the contents after the temperature is sufficiently lowered by leaving it for a certain period of time.

In the case of infants, it is more difficult than adults to eat hot food, so it is impossible for infants to directly consume food heated with an electric kettle. However, it is difficult to omit the operation of sterilizing beverages or baby food consumed by infants with an electric pot. This is because infants are more susceptible than adults to bacteria and viruses contained in food, and thus, if they consume food without sterilization, there is a high risk of infection with bacterial or viral diseases.

For this reason, parents should heat the food to 70 degrees or higher for sterilization when feeding a drink or baby food to the infant and then lower it sufficiently to a temperature that the infant can consume. The time required for cooling was excessive, which inevitably caused inconvenience to busy modern people. Accordingly, there is a demand for an electric pot provided with a cooling function so as to quickly lower the temperature of the contents.

Accordingly, when the switch unit 342 is pressed, the hub 311 may be rotated.

The shielding cover 310 may rotate between a closed position P1 for closing the heat dissipation hole 250 and an open position P2 for opening the heat dissipation hole 250 .

When the heating vessel 200 is in a state separated from the main body 100 (eg, the seating portion 120), the shielding cover 310 may be placed in the closed position P1. When the shielding cover 310 is in the closed position (P1), the cover 313 may cover and shield the heat dissipation hole 250 . The hub 311 and/or the cover 313 may be in close contact with the bottom surface 221b of the case 221 .

For example, the side surface 122 of the seating portion 120 has a vertical surface portion 122a formed vertically, and a chamfer portion 122b connecting the vertical surface portion 122a and the bottom surface 121 of the seating portion 120 . ) (or "sloping surface part"), and when the heating vessel 200 is seated on the seating part 120, the switch part 342 is the inner direction of the case 221 by the chamfer part 122b. can be pressurized. While the heating vessel 200 is seated on the seating part 120 , the switch part 342 may be continuously maintained in a pressurized state.

When the switch unit 342 is pressed, the shielding cover 310 may be rotated from the closed position (P1) to the open position (P2). That is, when the heating vessel 200 is coupled (or seated) to the main body 100 (or the seating portion 120 ), the shielding cover 310 may be placed in the open position P2 . When the shielding cover 310 is rotated from the closed position (P1) to the open position (P2), the pressing projection insertion groove 314 is pressed while maintaining the inclined surface 314a in contact with the upper surface of the pressing projection 330 . It may be moved in the circumferential direction of the hub 311 relative to the projection 330, and the upper surface of the pressing projection 330 may be in contact with the lower end of the inclined surface 314a of the pressing projection insertion groove 314. have. That is, the hub 311 may correspond to a state pushed upward by the pressing protrusion 330 . In other words, the shield cover 310 can rotate and translate upward while being changed from the closed position (P1) to the open position (P2). As the hub 311 is pushed up, the elastic member 320 may be further compressed and deformed.

In this way, since the shielding cover 310 is rotated and moved upward at the same time, the position change can be made more smoothly than if the cover 313 is in close contact with the bottom surface 221b of the case 221 and only rotates. can

When the heating vessel 200 is separated from the body 100 (eg, the seating unit 120 ), the pressure applied to the switch unit 342 may disappear. At this time, the restoring force of the elastic member 320 may press the shield cover 310 (or the hub 311 ) downward, and the pressing protrusion insertion groove 314 slides along the upper surface of the pressing protrusion 330 . The shielding cover 310 (or the hub 311) can be rotated and translated downward, and the shielding cover 310 (or the hub 311) which was in the open position P2 is automatically closed to the closed position P1. can be restored to The upper surface of the pressing projection 330 may be in contact with the upper end of the inclined surface 314a of the pressing projection insertion groove 314 .

In this way, the heat sink opening/closing device 300 can automatically open and close the heat sink 250 according to the separation and detachment of the heating vessel 200 and the body 100 , and the user enters through the heat sink 250 . It is possible to separate the heating vessel 200 and wash it without worrying about the heat transfer unit 220 breaking down due to the accumulated moisture.
